WATER-DRAIN F013 REFRIGERATOR-CABS.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed. July 11, 1913. Serial No. 778,600.

To all whom it may concern Be it known that I, Vroron C. VVnLLnn, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in W'aten Drains for Refrigerator-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in drains, and has particular reference to that type of such devices designed particularly for usage for refrigerating cars.

As its particular object this invention contemplates improvements which will act to collect the majority of sediment in the drain water before it enters the drain pipes which are in the preferred form of this invention arranged at the end of the refrigerating cars.

An object of equal importance with the foregoing is to form a novel formation of drain pipe constructed in such manner that the drain water will be conducted immediately to the exterior of the car.

A further object is to provide a novel form of strainer for the upper terminals of the drain pipes, so that any sediment collooted by the splash boards which are arranged on the bottom walls of the drain pan, will be prevented from entering the drain pipe with the resultant undesired clogging of this member.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views, of which similar reference numerals designate corresponding parts: Figure 1 is a longitudinal section taken through a portion of the refrigerating car and disclosing the drain pan and drain pipe of this invention in assembled relation. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a fragmentary top plan view of the drip pan.

Proceeding now to the description of the drawings the numeral 10 designates as an entirety the floor or bottom wall of the drip pan which is provided with the usual side and end walls 11 and 12, respectively. Mounted upon the upper surfaces of the side and end walls 11 and 12 are molding strips 12 adapted to seal the walls to the adjacent sides of the car. The members 10, 11 and 12 maybe made of sheet metal, wood or any other desirable material, and are preferably supported in spaced relationship to the floor 13 f the car by spacing bars or the like as at 1 The bottom wall 10 is equipped with a pair of longitudinally extending splash boards or ribs 15 and transverse splash boards or ribs 17. These members are disposed in spaced relationship to each other in order to better facilitate the drainage of the drip pan, and are in practice approximately one inch in height and preferably formed of strips of wood. 4

When the water drips down into the drip pan, the ribs 15 and 17 act to prevent the splashing of the water about the car, and also to collect a portion of the sediment in. the drain water. At each end of the drip pan is arranged. a strainer and sediment trap as at 18 and 19 in Fig. 3. These members 18 and 19 are similar in construction and reference will be had in detail to but one of them.

The drain pipe designated by the numeral 20 is formed of a suitable length of metal tubing which is directed through the floor 13 of the car and through the bottom wall of the trap and the flange or collar 23 mounted upon the lower end of the strainer pipe 20 rests upon the inner face of the bottom of the trap. A cylindrical strainer pipe 20 is fitted within the upper terminal of the pipe 20 and extends upwardly to a point slightly below the upper edges of the side and end walls 11 and 12.

The trap is suitably secured to the floor 13 about the drain pipe 20 and is preferably square in shape and is provided with a cover section 22 which is apertured centrally to permit the strainer pipe to extend slightly beyond the cover 22. A collar or washer 23 is mounted upon the strainer 20 interiorly of the member 21 and acts to hold the bottom wall of this member in the desired position on the bottom of the trap. The lower terminal of the drain pipe 20 is equipped with a sediment pipe 24 which is of the usual goose neck construction and is equipped with a pair of cleaning plugs and 26, the purpose ofwhich will be obvious. An attaching plate 27 is Welded or otherwise terminally secured to the pipe 20 and is arranged to be bolted or otherwise secured to the bottom face of the floor 13, as at 28, for the purpose of holding the pipe 20 in the desired assembled relation.

From the foregoing it will be apparent that while the water may freely pass down the drain pipe, into the trap 24, and through this out to the ground, the air will not be admitted to the drip pan. The trap 21 extends above the bottom Wall 10 of the drip pan and the cover plate 22 is perforated to increase the drainage efliciency of the device. The lower portion of the'trap 21 which is comprehended between the members 10 and 13 is imperforated.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, as the preferred embodiment is the most efiicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact. that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claim.

Having thus described my invention,

what I claim is:

The combination with a refri erator car 23 including a floor, a drlp pan positioned in said car and held at spaced distance from said floor, said drip pan comprising end and side walls, a plurality of splash strips secured longitudinally and transversely within said drip pan at spaced distance apart, a sediment trap substantially rectangular in shape positioned in said drip pan between the transverse and longitudinally extending strips and secured to the floor, the side walls of said sediment trap being imperforate, a top provided with a central opening, a drain pipe positioned through the floor of the car and through the central portion of the bottom of the sediment trap, a strainer pipe positioned through the central opening of the cover of the sediment trap, said strainer pipe having a collar formed thereon adjacent its lower end, said lower end of the strainer pipe extending downwardly into the drain pipe, and the collar limiting the downward movement of the same, said strainer pipe extending upwardly beyond the cover of the sediment trap, mold boards secured to the upper edges of the drip pan for forming a liquidtight joint, a sediment pipe secured to the lower end of the drain pipe, cleaning plugs in said drain pipe and sediment pipes to facilitate the cleaning of the same.

In testimony whereof I aflix my signature in presence of two witnesses.
